Family members of the Oregon high school shooter who killed another student before turning the gun on himself have broken their silence, saying they are "deeply confused and shocked" by their son's actions.

Michael Padgett and his ex-wife, Kristina, delivered a statement to the Fox TV affiliate in Portland on Friday, speaking out for the first time since their 15-year-old son, Jared, opened fire at Reynolds High School in Troutdale, where he fatally shot freshman Emilio Hoffman and wounded a teacher before taking his own life.

"We are at a loss as to how and why this tragedy unfolded," the statement read. "Our family does not condone and has never promoted violence or hatred toward anyone."

Jared Padgett walked into a locker room, where he shot and killed Emilio before shooting Todd Rispler in the hip. Despite his wounds, Rispler made it to the school's front office and started lockdown procedures.

Jared killed himself after a brief exchange of gunfire with officers.

Investigators have not determined a link between Jared and Emilio, who was 14.

"We are deeply sorrowful for the family of Emilio Hoffman and share their pain, heartache, and grief, for the loss of their oldest son and brother of the family," the statement said.
